yes, as I've read/followed some of 'yer' work. I recall something about an H-R 'topper' able to handle 'yer' LOAD!!! ,,,and/or,,,IS THAT JUST a LOAD? |

It is not a Topper which is a SB1 action, but the 12ga Ultra Slug gun as well as modern 10ga NEFs are SB2 actions, and are alloy steel and heatreated and can take a lot more. And in NEF 12ga Ultra with longer chamber and our brass case we get a 600gr slug to 2500. In same gun with 3.5" plastic case we get almost 2100 fps. Our secret is that we use slower powders than shotgun powders, thus keeping peak pressure down, but are able to use much more powder, for a longer taller average pressure curve, thus getiing more velocity. Same thing in our NEF 10ga testing.Ed |

The first 12GA FH was Robs on AR forum, my Savage was 2nd. Here is closeup pic of Rob's 12GA FH, a Borchardt falling block action. Real nice. In picture is along brass 12ga case with one of Rob's 2000gr bore rider, solid, streamlined slugs. Ed |

I'v got a .458 Win. Magnum,how is recoil compared to this ,in your 12 FH? I also got a link to your site.Would like verry much to shoot one |

Shooting a 600gr in my Savage at say 3000 is about like a full power load in a 8 lb 458. Savage is heavy, 23lbs.Ed |

Streamlined bullets should get good acuracy to 1000yds.and beyond.Siting upright would'nt be a problem with recoil,I'm not fond of muzzle breaks to Loud on the ears,Ialways wear hearing protection anyway,it would shure wake them up at the range.My .458 Win.Mag. always makes someone mad at the range.Any plans for a Magazine in the future? In most cases one would be enough for T REX or larger animals People ask me what I hunt with the .458,and I usualy smile and say anything I want.And for that reason I like verry much your 12ga.F-H.

Also --Here is picture of a dart type 12ga slug Rob made. Body is aluminum, it has a heavy tungsten carbide insert in the nose. The TC in the nose is about 5 times denser than AL. Total length is 2.35 inches, weight about 950 gr. The .75" long insert a real tight type fit. Heat AL, put in insert, cools, locks on. It is fairly streamlined, yet has wide meplat for penetration in game. Flat points penetrate straighter in game. It is hollow inside in the back, behind insert which puts the center of gravity way up front, it should fly straight even from a smoothbore. They are fast to make and material less expense than copper.In pic is a copper and a brass 600 cal slugs for comparison. Dart/slug on right has insert.Ed |

Here are more samples of nice 12ga slugs.....Here is pic of ones RG Henson sent. Jacketed 12ga. 715gr hollowpoints, on the right and in front a jkt 675gr hollowbase. RG's number 1-770-366-4846. These will be great for shorter plastic and brass cases as well as long cases. Other slugs in pic, in the back, left to right Foster 436gr- Dixie 600gr- 750gr brass- my 750gr hollowbase brass, and a hollowpoint I put a lightweight filler in the nose for streamlining..Ed |

Testing 715gr jacketed hollowpoint from RG Henson in Savage 210. With 30 inch barrel, long brass 3.85" case, big primer. Slightly hairy load 290gr RL22--2700 fps. Shot moderate load of 300gr W-860 -- 2400 fps for 3 shot group of 3" at 50 yards with my bad eyes and peep sights. They shoot nice, they go into target straight.. Other nice thing the price from RG, for customers getting in on his first run, $1.25 plus shipping. That is less than half of what other big bore jkt bullets cost. Call him for some great slugs. They are great like the Dixie slugs. Ed |

Lookee what another santa sent me. A regular BMG case on the left, and a straight BMG case on the right, and it CAME FROM THE MANUFACTURER THAT WAY. It is primer cartridge for large guns and howitzers. It is used in those guns/cannons that have powder in big bags. It is filled with powder and inserted into cannon breach and when fired sets off the larger charge. On some cannon breaches they have an automatic feed for these with a huge 40 round drum magazine. This on is marked IVI 89 C67. IVI is Canadian. On these breaches it is held by collet fingers for head space and for ejection. Ok, there are many thousands more of these out there than the PROP cases I showed before. We need to find few barrels of these and have Rob, etal, put on rims.... no annealing.....no fireforming, just slight resize to 12GA FH. Please help if you know of any. They would save so much work and time..And even though fired the bases are perfectly straight, another plus.....Ed |

Here is a picture of RG's jacketed 715gr slugs in various loads.First are 2.75" and 3" factory foster slugs\ for comparison. 3rd is jkt HP in 3.5" plastic case, 4th in a 3" brass RMC case. 5th in a 3.5" brass case with small primer, 6th in our long brass 3.85" case, big primer. Top hairy load in long case in Savage, 2900..Ed |

Please notice in the picture above, cases loaded with the 715 gr jacketed slugs, the 3rd and 4th ones. They both have same 90gr of 4227, same number of wads, shoot at 1700 in 24" NEF barrel. 3rd plastic is 3.5" case, the 4th brass is a 3" RMC. Both have shotgun primers.The 5th longer case is a 3.5" strong brass one I made from a PROP case, and when I put in primer bushing, I set it up for shotgun primer. I will test it with 4227 powder, 600gr and 715 gr slugs. Also in a couple months Rob, who's idea the 12GA FH was will be able to deliver the super strong 12GA FH cases made from BMG brass. And the they will be headstamped, all done by his CNC machine.Ed |

RIP on AR Big bore forum is doing 835 Mossy and 1400gr Darwin slugs. A 14.5 pound Ulti-Mag. The hollow part of the butt is filled with about 5.5 lbs of lead shot and epoxy. Has 4X Sightron in QRW rings. Do 3.5" plastic hulls with the Darwin in it first. It balances on the trigger. Loading the magazine with 4 and one up the spout will add about 1.25 pounds if the 5 rounds are "Darwins," and move the balance point to the front of the triggerguard. It is heavier rifled 24" chromoly alloy barrel. Brett in MN has Mossy 835, only with smoothbore barrel and gets 1oz finned plastic tail Ballistic Products slug to 2300 fps, using shotgun powder.Ed |

Still testing 8ga I have setup in the Enfield. It has a long smooth barrel. Those 8ga heavy plastic cases are great. Fire them 4 times with no resizing. Here is pic of slugs used in 8ga.. One and two are 1015gr hollowbase. Three and 4 are 875gr hollowbase. On four the cushion base is cut off so I can use card wad and have more room for powder.Ed |

We got our RMC 3.5" brass 12ga cases. These are turned cases using shotgun primer. They have nice thick base, and a good radius in the corner. Got a Brenekke OK 437 gr slug to 2800 fps, a 540gr Hammerhead slug to 2450. got 600gr Dixie to 2300, the 715gr RG jacketed to 2130, and a 1400gr Darwin to 1400 plus. Tested in NEF. Shot one case 15 times and still going strong, tight primer, with loads running about 20- 24,000 psi.I have pics of cases soon, and we also will test these brass ones and 3.5" plastic in 12ga Encore Prohunter..Ed |

Here is picture of RMC 3.5" cases with variety of slugs, locked on wad slugs and sabots. There are 3 of our long cases in back for comparison. The RMC turned cases have shotgun primer. Case # 4 has 437gr slug in BPI SABOT( finally hard sabots in 12ga for reloading), #5 437gr Brenekke KO slug, #6 540gr Hammerhead slug, #7 600gr Dixie hard slug, #8 RG's 715gr jacketed, #9 750gr solid brass.

Here is picture of a 12ga hard discarding sabot you can get for reloading, the BPI. From Ballistic products. In picture is sabot with a 437gr Hornady Great Plains 50cal slug I put in it. Also the 410 gr and 385gr Great Plains work. Finally able to load your own instead of paying 3-5 bucks each for loaded rounds.You can use the 500 S&W bullets also as well as shorter 50 cal blackpowder slugs... Ed |

Been testing the Encore with the Nef loads. Barrel breech is one inch same as muzzle, where the NEF is 1.200". It has dovetails cut out in bottom of the barrel for the nuts for the forearm screws. ... At the bottom of dove tail there is only .060" thickness. Before reaming had back one fill welded as it was where the taper for the forcing cone ended up with 3.5" chamber. I load it with 10 gr less powder than the NEF on all different slugs and weights. Like the BPI sabot in 3.5" plastic in NEF, 437 gr slug, 120gr 4227, 2400 fps, and in Encore 110gr 4227, 2270 fps. In 3.5" RMC brass case, same sabot/slug in NEF 140gr 4227, 2600+ fps,Encore 130gr 4227, 2500. The Encore is now 12 lbs, with hollow in butt and recesses in forearm with lead shot.In pic you see NEF And Encore with RMC brass cases started in chambers. Ed |

See what's possible, original Savage 210 action/stock the one I have our long case in. You can lengthen magazine in the plastic stock for up to 3.5" RMC brass cases, also 3.5" plastic cases. And you can open up bottom of the action to match, and the other things I did on the port, bolt travel, etc to feed cases. I did mine with heavy wood stock in singleshot. Using original plastic stock you weight the hollow butt. Trigger assembly on these is back to leave space for this. In picture you see stock original and stock mag longer. Second picture is a 3.5" brass case and slug overall length 3.7", in longer magazine. Brett in MN, who did this first used the regular follower and mag spring ok, it feeds ok for him. .. Ed ![]() |

Info to help loading BPI sabots in plastic,ok to use plastic overwad over powder, but should use cardboard card and nitro wads above that below the BPI sabot. Sabot doesn't tear up and accuracy much better. Personally I use cards over powder and nitro wads, And with used cases roll crimping onto the thin edge of sabot is uneven, so with my used cases I set the sabot and slug to right height and just redo the 6 point star crimp real hard, and the middle of all the crimp sectors set right on the flat nose of the slug in the sabot. I also do the same with RG's 715gr hollowpoint with the crimp sectors right on the hollowpoint in used cases. Roll crimping holds RG's slug in ok but its taper of the ogive and smoothness it doesn't open crimp all the way around when fired. The star crimp set slug at same height so you can get the same amount of powder. With RMC brass these are not problems but with brass to get good feeding from mag rounding front edge of mouth helps. Sectioned picture of RMC on right next to our long original case to show how well it is built thick and strong. One of cases has 20 firings, still good..Ed |

What others are doing hopping up loads and experimenting. Brett in MN uses a Mossy 835 12ga smoothbore turkey gun, but it is backbored 10ga size all the way out to end and has 10ga size choke, and he uses 12ga AQ 441gr slug with locked on basewad, from BPI. Using top rib bead sight only he can hit a pail 5 times in a row at 70 yds.Amazing accuracy for overbored barrel. He uses BPI X12X seal plastic wad, two 1/4" white felt wads, thin card then the AQ slug, with 65gr of Longshot getting 2200 fps. 3.5" new cases with roll crimp.......I asked him check it with a scope on it sometime. NFG from Greybeard and Shotgunworld with pump Mossy and 18.5" with slug barrel. He gets a 525gr Lyman over 1800 fps with 80gr of 4759/4227 powder. Hard alloy mix Lyman and shot one through 17" of pine. Shown in the pic below it mushroomed to .800" and only lost 8gr weight. It is a wasp waisted slug that is shot from a 12ga regular WW12 shotcup. The skirt of the slug collapsed into the underside of the nose. Many guys say that these are as accurate as most other stuff used. He used 3" plastic, PGS wad over powder and WW12 wadcup with slug it. He cuts wadcup petals back to length of the Lyman.In pic on left you see the Lymans with hollowbase up and the shape of it when starting out. Ok I am going to get Lymans to test and Longshot to test. Got to see if the Longshot will get further up in velocity than Blue Dot. Ed |

Here is a Savage 210 with bottom of action opened up toward the back, to take cases with 3.5" overall length. Slug Warrior on Shotgun World did it. Is similiar job the Brett in MN did, but he made his opening 3.7". I measured mine and they can be opened to 3.95". They also milled the rim guides back for controlling case feeding on longer cases. Ed |

Here is information and reason for keeping and milling the rim guides back for controlling case feeding on longer cases.Rim guides are angled in from the sides of the opening toward back. As the bolt pushes top case in the mag forward the back of case and rim comes to where the tapers widen out so the case then slides up in front of the bolt.I'm fixing up my 2nd Savage I have set up for my second 700H 3.25" belted case. Just to see how it will work and along with other guys doing it, get the info out to people. This work on the stock/action can be done in a vertical mill or good drill press. To use 3.5" plastic the opening on the action and magazine needs 3.25", for 2.875"" brass long loaded 3.5", if 3.5" brass about 3.7", if 3.5" brass long loaded, 3.95". By long loaded I mean a slug like the Dixie 600gr that protrudes up to .4".The 730 gr flat wide nose slug protrudes 1/8". You also have to widen and smooth the ramp going into the front bridge so case lifts smoothly on the way into chamber.Ed |

We get asked about putting brakes on the NEF Ultra. There is the concept called the internal brake that works nearly as good as expansion brake, with less back noise. Rob on AR did a couple with bunch of holes in the barrel in the end with the last 1.5" bored out .025" where holes go. Also many want more velocity in NEf and I added on a barrel section to mine. Combining Ideas we add smooth 9" section of bore extension, that is same as groove diameter and 1.5" end of that for internal brake. Eight 1/8" holes top and same 45 degees to each side.And we have over a 100 fps in velocity gain. And with card or wad behind load it will seal pressure going from rifled section to smooth. And these types of holes won't bother wads or sabots. My extension is a foot longer and gets 150 fps extra. No need for brake in mine as the gun is 17 lbs with extra bbl. Here is Rob's two he fixed up, and is shooting.He has them reamed out longer for long 3.85" case, weight added.Ed |

Here is a picture of porting holes in a 10ga NEF heavy long smooth barrel. Bbl 30" and 1.080" muzzle diameter behind the screw in choke area. This come with slightly extended screw in choke and is first 10ga with long barrel as heavy as my NEF 12ga FH short barrel was.. OR the short NEF 10 gauges with heavy barrel..It came with full and mod chokes. The other 10ga I tested earlier, only .960" at muzzle. I cut choke off and put it back in leaving the barrel an open bore for slugs and leaving an area 1.2" long for an internal brake to drill all the holes in like Rob did with NEFs in his picture. Now the 1.2" long area where holes are is bigger than needed for 10 ga so a reamer in the making will solve that and solve a major big bore project for me and others who asked me about using the short NEF 10ga for upgrade, which I didn't encourage putting all that work on a short barrel gun, with the amounts of powder that will be burnt in....are you ready.......THE 8GA FH....... I have 8ga FH loads tested in reworked Enfield.....Ed |

10 degrees back. and I don't use regular type expansion brakes as the noise is too much. The ports have some braking effect but more important reduces muzzle jump and gun twist quite a bit.I have run 770gr, 900gr, and 1025gr slugs so far in the 8ga testing.Ed |

More info on the heavy barreled gun we plan on making 8 gauge from. Nef SB2 103, 30" barrel, regular stock. 220 bucks. 100 bucks for shop to ream out to 8 ga smoothbore. Needs the 80 dollar thumbhole stock. Nice deal for a modern 8ga, using heavy duty plastic 3.3" long cases. I fired 6-8000 ft lb loads in one I made on Enfield, 4 times reloaded without resizing cases. Here is other project suggested by Boomie on the AR big bore forum, the 16GA FH. Cases made by me from bmg brass. Took 5 swagings, and two turnings on my case spinner lathe.Two Annealings Got couple cases made, in picture our 3.5" case and factory 16ga plastic case slug load. I'm getting test gun working now and as for a supply of cases you all will have to get with RMC if you want to rechamber a 16ga..Ed |

Here is picture of my NEF 12GA FH as it is now, A while back I got tired of short barrel and added a foot on to it. Used breech end of left over Savage and a sleeve. Lined up rifling and it has same twist and number of rifling. Hard way to do it. No need for rifling, or extra line up work. Run many loads and it adds 150 fps with VV110, 4759, and 4227 powders. Adds about a 100 with Blue Dot, and HS 7. Next one will be done different and easier. Next one will be a smoothbore add on piece of groove diameter, 10-12 inches long, make it one piece, 1 or 1 1/16" threads,about 1.2" diameter. Threaded 1.5" long on original barrel, and into add on piece, and will look like a brake and you could put in internal brake in the end.Ed |

Here is picture Stevens Revelation 350 16ga now a 16GA FH. It got a 385 gr to 2000, which is good for gun without a real heavy barrel. I lengthened chamber for the 3.5" brass cases pictured that I made from BMG brass. Anyone doing this can have cases made by RMC. Gun is weighted to 11 lbs. Action can handle more if barrel heavier.
